An improved ophthalmic instrument including an integral wavefront sensor and display device, wherein the wavefront sensor measures phase aberrations in reflections directed thereto to characterize aberrations of the eye and is operably coupled to the display device, which displays a graphical representation of the aberrations of the eye. Such graphical representation may include: two dimensional contour maps that graphically depict contribution of pre-specified terms (such as spherical aberration, astigmatism and coma) for the aberrations of the eye, coefficients corresponding to such pre-specified terms that characterize the aberrations of the eye, or predefined two-dimensional icons that provide a general graphical depiction of such prespecified terms. Such graphical representations provide the practitioner with valuable information characterizing the high order optical errors of the eye (which is far beyond the diopter information typically provided by current ophthalmic instruments) for use in diagnosis and treatment of abnormalities and disease in the eye.

The gaming machine may include a housing configured to carry a video display at an acute angle relative to a vertical datum, selected to optimize player comfort while carrying a video display so as to be visible as players enter a casino floor. In order to increase the number of gaming machines that can be placed in a given area of a casino floor, the gaming machine housing may be configured such that at least a portion of the side housing portions are non-parallel and converge toward each other, thus reducing the footprint of the machine.
